Korea Travel Essentials
Entry & visa, transit cards, money & payments, eSIM and emergency numbers — what's good to know before you come to Korea, all in one place.
Information as of 2026-11 · Rules and fees may change. This page is general guidance; if anything differs, the official sources prevail.
Entry & Visa
- Whether you need a visa or a K-ETA (Korea Electronic Travel Authorization) depends on your nationality and the purpose and length of your visit, and the rules change from time to time.
- Before you travel, always check the latest requirements for your nationality on the official websites below.
- Apply for K-ETA on the official website only. Look-alike agency sites exist, so double-check the address.
Transit Card
- A transit card such as T-money is a rechargeable card. Tap it on the reader when you board the subway or bus to pay the fare.
- You can buy and top up the card at convenience stores and subway stations. Accepted top-up methods (cash or card) may vary by location.
- For transfers you'd rather book in advance, such as airport rides, browse our transport products.
Money & Payments
- Most hotels, restaurants and shops accept international credit and debit cards. Carry a little cash for traditional markets and small shops.
- Exchange money at banks or licensed currency exchangers.
- Airport exchange counters are convenient, but their rates are often less favorable than in the city. Consider exchanging only what you need right away at the airport.
eSIM & SIM
- You'll need data for maps, translation and taxi apps as soon as you land. An eSIM can be installed before you leave home.
- Your phone must support eSIM, so check your device's compatibility before you buy.
Emergency Numbers
Dial these numbers anywhere in Korea — no area code needed.
